18216941 ÷ 419 
Our goal is to divide 18216941 by 419.

Step 1:
The number 419 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 419

Moving on to step 2:
419 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 419

Moving on to step 3:
182 divided by 419 is 0 with a remainder of 182.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 182 after subtracting 0 from 182.
Fetch the next digit (1) from the dividend, attach it to 182 and continue: 1821 / 419

Step 4:
When dividing 1821 by 419, we get 4 with a remainder of 145.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 145 after subtracting 1676 from 1821.
Take the next digit (6) from the dividend and append it to 145, then repeat: 1456 / 419

Step 5:
1456 divided by 419 is 3 with a remainder of 199.
Write down 3 as next digit of the result. 
Result so far: 43.0
The remainder is 199 after subtracting 1257 from 1456.
Bring next digit (9) of the dividend behind the 199 and repeat the process: 1999 / 419

Step 6:
419 can be fit into 1999 4 times, resulting in a remainder of 323.
Put 4 as the next digit of the answer. 
Result so far: 434.0
If we subtract 1676 from 1999, we get 323.
Fetch the next digit (4) from the dividend, attach it to 323 and continue: 3234 / 419

Going ahead to step 7:
3234 divided by 419 is 7 with a remainder of 301.
Write down 7 as next digit of the result. 
Result so far: 4347.0
Subtract 2933 from 3234 to get 301.
Fetch the next digit (1) from the dividend, attach it to 301 and continue: 3011 / 419

Moving on to step 8:
419 goes into 3011 7 times with a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 43477.0
If we take 2933 away from 3011, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 9:
When dividing 780 by 419, we get 1 with a remainder of 361.
The number 1 becomes the next digit in our result. 
Result so far: 43477.1
Subtracting 419 from 780 leaves us with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

On to step 10:
When dividing 3610 by 419, we get 8 with a remainder of 258.
The next digit of our result is 8. 
Result so far: 43477.18
Subtracting 3352 from 3610 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 11:
If we divide 2580 by 419, we get 6 and a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 43477.186
The remainder is 66 after subtracting 2514 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 12:
419 can be fit into 660 1 times, resulting in a remainder of 241.
The number 1 becomes the next digit in our result. 
Result so far: 43477.1861
Subtract 419 from 660 to get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Let's proceed to step 13:
The number 419 fits into 2410 5 times, leaving a remainder of 315.
Use 5 as the next digit of our solution. 
Result so far: 43477.18615
The remainder is 315 after subtracting 2095 from 2410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 14:
The number 419 fits into 3150 7 times, leaving a remainder of 217.
Record the quotient 7 as the next digit in the result. 
Result so far: 43477.186157
Deduct 2933 from 3150 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 15:
419 goes into 2170 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 43477.1861575
If we take 2095 away from 2170, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 16:
The number 419 fits into 750 1 times, leaving a remainder of 331.
Write down 1 as next digit of the result. 
Result so far: 43477.18615751
If we subtract 419 from 750, we get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

After the division, we end up with 43477.18615751 and a remainder of 3.31e-07.
